That's just silly. The lab is necessary because the world outside the lab is contaminated with biota to the remotest and seemingly most inhospitable corner. The facts that emerge are supportive.
Your grumbling about "assumptions" would be more appropriate if I had claimed "proof" instead of "evidence." But evidence was your word, the lack of same supposedly buttressing your claim of abiogenesis as a faith. But evidence there is, and a lack of viable, non-spooky alternative models.
You err. I claim assumption of something, namely a pre-biotic soup, without evidence is like faith. I do not accept a lab experiment as evidence of that specific condition any more than I would use a can of Campbell's chicken broth as that evidence. Traces of chemicals or structures formed by crystallization of various compounds would be evidence of said culinary delight.
